摘要
湿地生态系统健康评价是判断湿地结构功能完整水平的重要方法。文章从水环境、土壤、生物、景观和社会5个方面提取13项评价指标构建湿地生态系统健康评价体系,评测阅海国家湿地公园生态系统健康状况,明确系统要素的贡献程度并识别健康威胁因子,以期为指导阅海湿地生态修复及保障湿地公园系统可持续发展提供科学依据。结果表明,阅海国家湿地公园生态系统综合健康指数为3.893,呈中等健康水平;一类指标权重贡献表现为景观指标>水环境指标>生物指标>社会指标>土壤指标,二类指标中野生动物栖息地指数权重贡献最大。地表水质恶化、水源保证率低、野生动物栖息环境缺失因素等严重威胁阅海国家湿地公园生态系统健康,建议组建水资源联动管理体系并形成生态水位协调机制以提升阅海湿地生态系统健康水平。
Ecosystem health assessment,an important method to judge the integrity level of wetland structure and function.In order to identify the ecosystem health in Yuehai National Wetland Park(YNWP),defining the contribution degree of system elements and identifying health threat factors and provide scientific foundation for guiding the ecological restoration and sustainability of YNWP,the structural model of wetland ecosystem health assessment was constructed.The results showed that the comprehensive health index of the YNWP was 3.893,which showed a medium health level.weight of firstly indicators were landscape index>water environment index>biological index>social index>soil index.Among the secondary indicators,the weight contribution of wildlife habitat index is greater.Water degradation,insufficient water supply and lack of habitat are causes of threaten the ecosystem health of YNWP.Suggest that establish an integrated water resources management and ecological water level coordination systems to improve the ecosystem health of YNWP.
